Great Works River Managment Plan Great Works River Nonpoint Source Pollution Watershed Management Plan A Maine Department of Environmental Protection 319 Nonpoint Source Pollution Control Project Prepared by York County Soil & Water Conservation District January 2007 1 2 Great Works River Watershed Management Plan - January 2007 Great Works River Watershed (GWR) Nonpoint Source Pollution Management Plan Prepared by Forrest Bell, York County Soil & Water Conservation District in cooperation with the Great Works River Watershed Coalition, and the Maine Department of Environmental Protection. This project was funded, in part, by an EPA Section 319 grant. January 2007 The mission of the York County Soil & Water Conservation District is to provide technical, educational, and financial resources to land users in York County to promote a quality of life, stewardship and wise use of our natural resources and ensure the viability of the agricultural sector. Contact: York County Soil & Water Conservation District 21 Bradeen Street, Suite 104 Springvale, Maine 04083 207-324-0888 email: [email protected] I would like to personally thank the individuals on the following page for providing outstanding community support in this watershed and region. The citizen volunteers tirelessly assisting the GWRWC, Bauneg Beg Lake Association, York Co SWCD Board, local land trusts, and local municipalities are a true inspiration to all of us working in the conservation and environmental management field. It is obvious that one of the most important resources in this watershed is its citizens. - Forrest Bell, Project Manager i Great Works River Watershed Management Plan - January 2007 Acknowledgements GWRWC Steering Committee Mike Cannon, South Berwick Nancy Freese, Noble HS Katie Goulet, North Berwick Malcolm Child, South Berwick Ray Smith, North Berwick, BBLA Forrest Bell, York County SWCD Watershed Survey Volunteers Debbie Briggs Bob Hoey Sarah McNair Jeff Brinck Lorraine Hoey Jodi Michaud Bill Bullard Julie Hundley Dwight Montague Laurie Callahan Bruce Jordan Dick Moore Erica Carlsen Shiela Jordan Jan Moore Brad Christo Don Kale Jamie Schoedinger Jean Demetracopoulos Thomas Keating Sarah Schoedinger John Demeteracopoulos Jack Kelleher Marilyn Smith-Church Betsy Finigan Debbie Kreis Rick & Kiki Stevens Donna Flint David Ladd Deb St. Pierre Margo Foreman Tony Lombardi Tin Smith John Forshay Richard Lovejoy Jeff Varricchione Teegan French Nancy Lowenberg Bayse Andra Ventimigelia David Gagnon Fred Luiggi Tony Welch Wendy Garland Linda Luiggi Bill Whaley Heather Girard Renie Martin Ann Whitten Kate Goulet Dan May GWR Watershed Coalition Steve Gray Sue May Owen Hill Jim McGuire Technical Staff Additional Reviewers Forrest Bell, YCSWCD Don Kale, Maine DEP Jennifer Jespersen, FB Environmental Tin Smith, Wells NERR Tricia Rouleau, FB Environmental Mike Cannon, GWRWC Fred Dillon, FB Environmental Wendy Garland, Maine DEP Nancy Freese, GWRWC Glenn Wilde, YCSWCD Ray Smith, BBLA Project Funding and Support Maine Department of Environmental Protection US Environmental Protection Agency ii Great Works River Watershed Management Plan - January 2007 Table of Contents Acknowledgements ....................................................................................... ii List of Figures ............................................................................................... vi List of Tables................................................................................................. vii List of Maps .................................................................................................. viii Key to Abbreviations ……………………………………….…………….……… ix 1.

  • Introduction
    Mousam River near Sanford, Maine The majority of sampling effort in the Salmon Falls basin has focused on stations on the mainstem affected by dams and wastewater discharges. The Salmon Falls River has been managed as Class B for many years but has experienced continual problems attaining Class B standards for dissolved oxygen, bacteria and aquatic life, in the lower reaches,. All aquatic life monitoring stations downstream of the Berwick sewage treatment plant fail to attain assigned Class B standards. Introduction Geography The Saco River basin covers 1,696 square miles. The River originates at Saco Lake just north of Crawford Notch, New Hampshire and flows through the Mt. Washington Valley. About half of the drainage area is in the State of New Hampshire. Just east of Conway, New Hampshire it crosses into Maine, near Fryeburg, winds northeast for a short distance, and then meanders south- southeast through the mountains and hills of Western Maine. The Saco River continues southeast towards the urban coastal areas of Biddeford and Saco before emptying into Saco Bay. The total length from the Maine/New Hampshire border is approximately 85 miles. There are four other sampled streams in the Saco River basin listed in Basin Table 9. The Piscataqua/Salmon Falls River basin covers 1,356 sq. miles. The Piscataqua River is the tidal portion of the Salmon Falls River. The Biological Monitoring Program has not conducted any sampling in the tidal portions of the river so the remainder of this report will focus on the Salmon Falls River. For its entire length, including below head of tide, the River forms the Maine/New Hampshire border.

  • Little Ossipee River, Connecting the Towns of Waterboro and Limerick, Maine
    HYDROLOGY REPORT Stimson Bridge carries State Route 5 over the Little Ossipee River, connecting the towns of Waterboro and Limerick, Maine. The Little Ossipee River begins in Acton, Maine at Balch Pond Dam and flows northeast for approximately 30 miles to its confluence with the Saco River in the town of Limington, Maine. The Little Ossipee River is approximately 120 feet wide at the location of Stimson Bridge, which is located approximately 14.3 miles upstream of its confluence with the Saco River. The drainage basin characteristics for the bridge are based on the comparison of projected peak flow rates from three sources. The first source is a 2007 report on the estimated magnitudes and recurrence intervals of peak flows on the Mousam and Little Ossipee Rivers for the flood of April 2007, with the estimated peak flows generated using the Expected Moments Algorithm (EMA) (Cohn and others, 1997; Cohn and others, 2001; Griffs and others, 2004) and the flows from the April 2007 flood. The second source is the Maine Department of Transportation (MaineDOT) Environmental Office – Hydrology Section which provided peak flows computed using the 1999 U.S.G.S. full regression equation. The third and final source is the Federal Emergency Management Agency (FEMA) flood insurance study for York County Maine, which generates peak discharges from a county wide analysis using drainage area relationships for the entire County. The three sets of peak flow data were further examined in cooperation with Charles Hebson from the MaineDOT Environmental Office ‐ Hydrology Section, where it was determined that the peak flows from the 2007 report using the EMA estimates were the most appropriate as it is the most up to date analysis of the Little Ossipee River.
